Default props for 3d???
Ok Guys,

I'm currently running a phoneix extra 330s w/ST 90 12x9 prop on it. I live in denver(alt 5500) and am curious as to why props for 3d manuves are the 4-6 pitch variety. Is it to purely keep the RPM's up? How much different would my plane handle if I went from a 12x9 to a 13x4 or 13x5?

Thoughts?
